Question

construct a discrete frequency series with the help of following data given
8,12,15,18,12,15,20,22,15,25
30,15,10,15,27,30,15,10,15,20​

Answer 1

Explanation:

Objects that impact our environment are:

(i) Factories

(ii) Animals

(iii) Human beings

(iv) Automobiles

(v) Fuel

(vi) Coal

(vii) Soil

(viii) Fertilisers

(ix) Trees

(x) Plastic

The above objects can be classified as:

a) Living- Animals, human beings, trees

b) Non-living- Factories, automobiles, soil, fuel, coal, fertilisers, plastic

No, it is not a quantitative classification as we cannot classify the data on the basis of numerical values into different classes or groups. This is because we cannot judge in numbers the impact of objects on environment.
